As stated before, GF’s Bestie was always teasing me and though she had blown me, I hadn’t had anything else yet. We would hang out and have drinks regularly on the weekends. I still don’t know if they were planning all of this prior or my GF just manipulated her to act. One weekend we were grilling after a long day at the pool. My GF had passed out on our bed and I was outside grilling. Bestie comes out and starts flirting as usual. Low cut shirt with huge tits and she knew how to move them around for me. She asks if I want to play with them as she pulls the shirt low so they pop out. I immediately reach and start playing and licking them. At that point she pulls back and leans over a chair while lowering her shorts. I pull myself behind her and slide in easily since she was so wet. It’s tight but it’s like she is caressing me from the inside. I’m just thrusting away at this point and she keeps pushing back. It feels so good sliding into her. She tells me to stop and I’m thinking she’s feeling guilty but she just kneels, takes me all the way in and gets me to cum down her throat.
